​​Introduction to cm-locale-de_DE-12.5.1.8000-1.cop.sha512 Software​​

This cryptographic-signed language pack provides standardized German (de_DE) localization for Cisco Unified Communications Manager (CUCM) 12.5(1), designed to meet regulatory requirements under Germany’s Telecommunications Modernization Act 2025. It enables precise translation of 2,300+ interface elements across administrative consoles, endpoint device configurations, and API error handling systems.

Released on September 15, 2025 (build 8000-1), the package resolves 41 localization defects from previous iterations, including compound noun hyphenation errors in Cisco Jabber and DIN 5008-compliant date/time formatting for audit logs. Mandatory SHA512 checksum validation ensures installation integrity, aligning with FIPS 140-3 security standards.
